NSW jury discharged in teacher sex case

A jury has been discharged on the first day of the trial of a Sydney high school teacher accused of sex offences against three students.

Cameron White, 39, has pleaded not guilty to multiple counts of aggravated sexual intercourse with a person aged between 14 and 16 years, multiple counts of sexual intercourse with a person under care and one count of aggravated acts of indecency against a person aged under 16.

His trial was scheduled to begin in the NSW District Court on Wednesday but the jury was discharged for legal reasons part-way through crown prosecutor Michael Barr's opening address.
